Trish is ordering t-shirts from a website that charges a certain amount per t-shirt plus a flat rate for shipping. The cost for a given number of t-shirts is shown in the table. 20a. Write an equation to represent the situation. (Write your answer with no spaces, all lowercase letters, and write the slope as a decimal)

20b. What does the slope mean in the context of the situation?

20c. What does the y-intercept mean in the context of the situation?

Step-by-step explanation:

What is an equation of the line in slope-intercept form?

m = two-sevenths and the y-intercept is (0, -12)

y = 2/7 x- 12.

What is the graph of the equation?

2x - y = 2

Graph C.

Write an equation of the line, in point-slope form, that passes through the two given points.

points: (-2, 15), (9, -18)

y - 15 = -3(x + 2).

Write an equation of the line, in point-slope form, that passes through the two given points.

points: (8, -8) ; slope: 3

y + 8 = 3 (x - 8)

What is the equation of the given line in standard form? Use integer coefficients.

y = -1.7x + 8.5

17x + 10y = 85

What are the intercepts of the equation? Graph the equation.

5x + 3y = 15

x-intercept: (3, 0)

y-intercept: (0,5)

You are trying to compare the Fahrenheit and Celsius scales and you have two examples: Temperature A is 50 degrees Celsius and 122 degrees Fahrenheit. Temperature B is 100 degrees Celsius and 212 degrees Fahrenheit. What graph models the relationship between the Fahrenheit and Celsius scales? What is an equation of the line in slope-intercept form?

C.

20a. y = 8.75x - 5.99

20b. slop is the cost of each shirt.

20c. I am not to sure on this one so I am going to guess that it means payment to enter the shop.

Step-by-step explanation:

I hope this helps if not I am so sorry.

The first step is to isolate the constants on one side of the equal sign

Step-by-step explanation:

9x - 7 = 10

The first step is to isolate the constants on one side of the equal sign

9x - 7 = 10

    +7     +7

9x = 17

9    9

x = 1.8
